the most potent inhibitory activity by IC50 = 0.74 μM while 6-farnesyloxy-3-carboxycoumarin was the weakest inhibitor among farnesyl analogs (IC50 = 10.4 μM). Bonding affinity of the designed molecular structures toward 15-LOX-1 3D structure complexed with RS75091, as potent 15-LOX-1 inhibitor, was studied by utilizing docking analysis. There was a direct relationship between lipoxygenase inhibitory

生物表现出有效的抑制活性。5-法呢烷氧基-3-羧基
香豆素显示出最强的抑制活性,IC50 = 0.74μM,而6-法呢烷氧基-3-羧基
香豆素是在法呢基类似物中最弱的
抑制剂(IC50 = 10.4μM)。通过对接分析研究了设计的分子结构对与RS75091复合的15-LOX-1 3D结构的键合亲和力,RS75091是有效的15-LOX-1
